of_get_regulator_init_data(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual entry for of_get_regulator_init_data — and yes, this function is literally here to extract regulator_init_data structure info. it's giving “get the regulator init data out of the device tree” energy ✨

---

🌸 SYNOPSIS 🌸

struct regulator_init_data * of_get_regulator_init_data (struct device
       *dev , struct device_node *node , const struct regulator_desc *desc );

---

🎀 ARGUMENTS 🎀

• dev — the device that’s requesting the regulator_init_data, bestie 🫶
• node — the regulator device node, aka the device tree node in question 🌳
• desc — the regulator description, no cap 💅

---

🦋 DESCRIPTION 🦋

so this icon populates a regulator_init_data structure by extracting data from a device tree node. that’s the whole vibe: device tree node goes in, populated regulator_init_data structure comes out. slay ✨

---

⭐ RETURN ⭐

it returns a pointer to a populated struct regulator_init_data — or NULL if memory allocation fails. yep, that’s the one caveat, bestie 😭
